CVE-2025-36320
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedIBM watsonx.data intelligence 5.2.0, 5.2.1, 5.2.2, 5.3.0 is vulnerable to stored cross-site scripting. This vulnerability allows an authenticated user to embed arbitrary JavaScript code in the Web UI thus altering the intended functionality potentially leading to credentials disclosure within a trusted session.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceStored cross-site scripting (XSS) vulnerability in IBM watsonx.data intelligence Web UI allows authenticated users to inject malicious JavaScript code that gets stored and executed in the browsers of other users viewing the affected content, potentially leading to session hijacking and credentials disclosure.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm IBM watsonx.data Intelligence installationIdentify whether IBM watsonx.data Intelligence is deployed in your environment by checking for running processes, installed packages, or container images related to the productAffected if The product is present in the environment
-
Verify Web UI component is enabledCheck if the watsonx.data Intelligence Web UI service is running and accessible. Typically the UI is exposed on port 9443 or configured HTTPS ports. Review your network configuration and service definitions.Affected if The Web UI is exposed and accessible to users
-
Confirm authentication is configuredReview authentication settings for the watsonx.data Intelligence deployment. Check whether user authentication (such as LDAP, SAML, or internal auth) is enabled for the Web UI.Affected if Users can authenticate to the Web UI, as authenticated users are required to exploit this vulnerability
-
Inspect stored content for XSS payloadsExamine any user-generated content stored in the system (such as queries, metadata, or configuration entries) that gets displayed in the Web UI. Check database tables or storage where user input is persisted.Affected if Malicious JavaScript scripts are found stored in user-controllable content fields displayed in the UI
-
Review Web UI access logsAnalyze Web UI access and error logs for evidence of script injection attempts or unusual HTML/script content in user input fields.Affected if Logs show XSS injection patterns or unexpected script tags in user-submitted data
Your environment is affected if IBM watsonx.data Intelligence is deployed with its Web UI enabled and accessible to authenticated users, regardless of version.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply vendor patch when available. Implement robust server-side input validation and output encoding for all user-supplied content displayed in the Web UI. Consider implementing Content Security Policy (CSP) headers as defense-in-depth.
